Interface Reference

The Audio Ribbon Editor interface is divided into the main toolbar, the ribbon list, and the inspector panel for the selected ribbon.

Main Toolbar

Located at the top of the window, these controls affect the tool state or all ribbons.

Control	Description
Add New Ribbon	Creates a new audio ribbon and enters drawing mode. Click on the terrain to place nodes.
Remove All	Deletes all ribbons in the scene. This action can be undone via the Edit menu.
Lock Shape	Toggles between Node Editing and Rigid Movement. - Unlocked: You can select and move individual nodes to reshape the path. - Locked: The ribbon maintains its shape, and the gizmo moves the entire object at once.
Toggle Gizmo	Shows or hides the 3D transform gizmo for the selected node or ribbon.

Displays all audio ribbons in the scene.

Selection: Click a row to select that ribbon for editing.
Name: Click the text field to rename the ribbon.
Visibility: Toggle the “Eye” or “Lock” icon to Enable/Disable the ribbon’s audio.
Delete: Click the trash icon to remove the specific ribbon.

Controls for the currently selected ribbon.

Control	Description
Go To Ribbon	Moves the camera to focus on the selected ribbon.
Conform to Surface	Snaps all nodes of the ribbon to the highest surface below them. Checks Terrain, River Objects, and Water Planes and snaps to whichever is highest.
Quad/Single	Toggles between Single Emitter (Ambient) and Quad Emitter modes.
Up/Down	Flips the vertical orientation of the ribbon (useful if the “Top” surface is facing the wrong way).
Surface/Volume	Toggles between using the ribbon as a 2D Surface (flat) or a 3D Volume (ellipsoid).

Speed (m/s): A global parameter sent to the audio engine. This often controls the pitch or flow speed of the sound event.
Depth (m): Sets the vertical depth/thickness of the ribbon.
- In Volume Mode, this defines the vertical range where the sound is at max volume.
- In Surface Mode, this offsets the emitter from the base node position.

This section allows you to bind FMOD events to the emitter channels. All events must be valid FMOD event paths (e.g., event:>Ambient>...).

Front / Rear / Left / Right: Individual event paths.
- Front: Sound heard when looking along the flow.
- Rear: Sound heard when looking against the flow.
- Left/Right: Sounds heard from the banks/sides.
Mute Controls: Individual mute toggles for each channel. Use these to verify your spatial setup (e.g., mute everything but “Front” to ensure the sound source is behaving as expected).
